[0029] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0031] It will be appreciated that spatial relationship terms such as "under", "beneath", "below", "under", "above", "above", etc., may be used herein to describe the relationship of an element or feature shown in the figures to other elements or features. It will be appreciated that, in addition to the orientations shown in the figures, spatial relationship terms also include different orientations of the device in use and operation. For example, if the device in the accompanying drawings is flipped, an element or feature described as "under other elements" or "under it" or "under it" will be oriented as being "on" the other elements or features. Thus, the exemplary terms "under" and "under" may include both upper and lower orientations. In addition, the device may also include additional orientations (e.g., rotated 90 degrees or other orientations), and the spatial descriptors used herein are interpreted accordingly.

[0032] See also Figure 1-4 A grinding device includes an equipment body 1, a grabbing assembly 2 and a positioning assembly 3. The grabbing assembly 2 includes a lifting portion 21 arranged on the equipment body 1, and the lifting portion 21 is provided with a mounting frame 22 located above the feed hopper of the equipment body 1. The mounting frame 22 is provided with grabbing portions 23 distributed in a circular array, and one end of the grabbing portion 23 extends into the feed hopper of the equipment body 1. The positioning assembly 3 is arranged on the lifting portion 21 and the grabbing portion 23 for positioning the grabbing portion 23.

[0033] Based on the above, this embodiment forms a material dispersing structure driven by the lifting part 21 on the feed hopper of the equipment body 1 through the combination of the mounting frame 22 and the grabbing part 23. When the lifting part 21 drives the mounting frame 22 to move slowly into the feed hopper of the equipment body 1, the grabbing part 23 moves toward the middle under the action of the gradually narrowing end of the feed hopper of the equipment body 1, and begins to gather and grab the waste tires. When the lifting part 21 rises rapidly in the opposite direction, the grasping part 23 that moves closer drives the gathered waste tires to rise, and at the same time, the grasping part 23 opens, and the waste tires are dropped again. While the lifting part 21 is rising, the positioning component 3 operates to position the grasping part 23, drives the waste tires to rise to a certain height, and then the positioning component 3 opens the grasping part 23 to drop the waste tires, so as to achieve loosening of the equipment processing or reduce the accumulation of waste tires, avoid blockage of the equipment feed, and perform normal grinding processing.

[0034] See also Figure 1-4 The lifting part 21 includes a guide rail 211 symmetrically arranged on the equipment body 1 , a support member 212 is arranged between the guide rail 211 and the equipment body 1 , and a driving member 213 is arranged between the equipment body 1 and the support member 212 .

[0035] The lifting part 21 drives the installation frame 22 to rise and fall, and the driving member 213 is preferably an electric hydraulic cylinder, and ear plates are arranged on both ends, which cooperate with the connecting columns respectively installed on the equipment body 1 and the support member 212, and are rotatably installed between the equipment body 1 and the support member 212, and the connecting columns are installed on the corresponding support member 212. The guide rail 211 adopts a combination of rail rods in groups of two, and there are intervals between the rail rods, so that the connecting columns on the support member 212 can pass through the guide rail 211 and cooperate with the driving member 213 to drive the support member 212 to move on the guide rail 211.

[0036] Taking into account that the support member 212 connected to the mounting frame 22 is arranged above the feed hopper of the equipment body 1, the support member 212 of this embodiment includes a trunk 2121 that can slide along the guide rail 211, and a fork plate 2122 is arranged on the trunk 2121, and an extension plate 2123 is arranged on the fork plate 2122. The fork plate 2122 and the extension plate 2123 are both located above the feed hopper of the equipment body 1, and the fork plate 2122 is adapted to the equipment body 1.

[0037] The main trunk 2121 and the extension plate 2123 are connected by the arched design of the fork plate 2122. The space vacated by the arch of the fork plate 2122 just corresponds to the feeding edge of the equipment body 1. The main trunk 2121 is lowered to drive the installation frame 22 to move into the feed hopper of the equipment body 1, which can increase the movement stroke of the grabbing part 23 into the feed hopper of the equipment body 1.

[0038] See also Figure 1-4The mounting frame 22 is arranged above the feed hopper of the equipment body 1 through an extension plate 2123, and the grabbing portion 23 includes a side plate 231 arranged on the mounting frame 22, one end of the side plate 231 extends into the feed hopper of the equipment body 1, and a top support block 232 is arranged on the side of the side plate 231 relative to the feed hopper of the equipment body 1.

[0039] Based on the installation frame 22, the grabbing part 23 is driven to move in the feed hopper of the equipment body 1. One end of the side plate 231 of the grabbing part 23 is connected to the installation frame 22, and the other end is placed on the inner wall of the feed hopper and is inclined. When the side plate 231 moves into the feed hopper, the side plate 231 moves toward the middle with the gradually narrowing feed hopper, and the waste tires in the middle are gathered. After the top support block 232 contacts the feed hopper, the side plate 231 continues to move toward the middle, and finally completes the grasping of the gathered waste tires. Finally, the driving member 213 is quickly reset, driving the gathered waste tires to rise quickly, reducing the accumulation of waste tires fed out of the feed hopper, and then naturally unfolds, and the waste tires fall back.

[0040] See also Figure 1-4 The positioning assembly 3 includes a power member 31 arranged on the fork plate 2122, the output shaft of the power member 31 passes through the extension plate 2123, a connector 32 is arranged on the output shaft of the power member 31, an outer support rod 33 is arranged on the connector 32, the outer support rod 33 surrounds the outside of the side plate 231, and the outer support rod 33 is in contact with the side plate 231.

[0041] When the side plates 231 are brought together to gather the waste tires, the power member 31, which is also an electric hydraulic cylinder, can drive the connecting head 32 to rise upward, drive the outer support rod 33 to move and reconnect with the side plates 231, and limit the positioning of the side plates 231 after they are brought together. Subsequently, the gathered waste tires are lifted up under the drive of the driving member 213 to achieve temporary storage of the grabbed waste tires. When the amount of waste tires accumulated in the feed hopper is less, the power member 31 can drive the outer support rod 33 to open the side plates 231 and drop the waste tires back.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
